About this map

Hyampom sits at the confluence of Hayfork Creek and the South Fork Trinity River, a remote settlement point where the river valley widens slightly before tightening into steep mountain terrain. This 1982 survey illustrates a landscape of deep canyons and prominent ridges, including Pelletreau Ridge and South Fork Mountain. The map details a network of family-named agricultural outposts such as Marcels Ranch, Gret Ranch, and French Ranch, which follow the narrow benches and flats along the river, including Wintoon Flat and Waldorff Flat.

Outside of the immediate river corridor, the terrain within the Trinity National Forest is defined by drainage systems like Pelletreau Creek and Butter Creek, the latter containing the Butter Creek Caves. These areas are accessible only by a few scattered roads and a system of Jeep Trails and Foot Trails, indicating a persistent isolation for the few inhabitants of the high-country camps such as Snow Camp.
